Investor read

• This is a 2-bed/1.0-bath single-family listed at $1.32M.
• At list price, monthly cash flow is $2k ($29k/yr) — positive.
• The deal already cash-flows at list — no discount required.
• Meets the 1% rule at list price ($15k rent vs $1.32M).
• It's been on market 187 days — a 12% lower offer ($1.17M) is reasonable based on typical stale-listing flexibility.
• Recommended offer: $1.17M (12.0% below list) — sets the bar for market timing.
• Local home prices are declining (-3.0%/yr); year-one equity from $9k of loan paydown is wiped out by about $40k of value loss. Plan a longer hold.
• Location reads 69/100 on livability (#472 in NY) — a middle-class / working-renter tenant base. Strengths: crime A+, employment A+; Watch: commute D+, amenities F, cost of living F.
• Southampton Union Free School District (suburban): math 53% / reading 51% proficiency, ranked #293 of 590 in NY (top 50%) — acceptable for families but not a draw, mixed tenant base, ~2y average lease.
• Market conditions: Rents rising fast (+14.6%/yr); 96 active listings in the ZIP; 2 comparable units currently listed for rent nearby; high-income renter base; 1,366 units permitted in Suffolk County in 2024 (216 in 5+ unit buildings).
• Suffolk County population projected to shrink 5% by 2050 — rents likely to lag national; underwrite the cash flow, not the appreciation.
• 2 sale attempts since 2y ago; this cycle's ask has dropped $170k (11%) from the opening price — seller is motivated, your offer sets the floor, not the list.
• Current owner paid $330k; list at $1.32M implies a 302% gain — meaningful room to come down on a strong offer.
• At projected returns (-3.0% appreciation + 8.0% rent growth), your $371k cash investment doubles in ~8 years — after that, you're playing with house money.
• Climate carrying-cost: severe wind risk, 80% chance of damaging wind over 30y; extreme-heat days projected 7→22/yr by 2055 (HVAC capex compounding) — expect insurance premiums to compound above CPI over the hold.
• Cap rate 8.5% vs local median 2.8% in Southampton — top-decile yield for the area; either an underpriced asset or a hidden risk that comps aren't pricing in. Stress-test before assuming the spread holds.
• At $14,688/mo this rent would consume 113% of the median local household income ($156k/yr) (locally 274% of renters already pay >50% of income on rent) — very limited rent-growth headroom before tenants either downsize or default.

Questions for listing agent

• It's been on market 187 days. Have you received any prior offers? Is the seller open to a 12% concession, seller financing, or rate buy-down credit?
• Why hasn't it sold? Are there any deal-killer items the seller is aware of (foundation, flood, title, zoning, code violations)?
• Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
• What's the average days-on-market for RENTAL listings here right now (not sales)? A rising rental-DOM trend means longer vacancies and softer asking-rent achievability than the comps imply.
• What's the recent tenant-quality profile in this submarket — average credit score on applications, eviction rate, late-payment / NSF rate, and stable-employment percentage? A property-management company in the area should have these aggregated.
• How much new for-sale + rental construction is in the pipeline within 1–3 miles? Heavy new supply typically softens prices + rents 12–24 months out; constrained supply supports both.
